This slide presentation outlines a study on the status and research needs of main break models. The presentation begins with a review of main break modeling that includes research on main break prediction, and then lists results of a utility survey. Findings of modeling main breaks are listed. The presentation highlights Rogers' 2006 study thatdeveloped an approach based on frequencyof breaks, and used a performance-based approach toestimate the present and future state ofpipe segment from maintenance data. Topics covered include: pipe groups; probabilistic module; MCDA tool; test results; Rogers' Model Schematic; model wrap up; planning for water main renewal; conservative strategy; point systems; utility actions; and, water supply industry research. Includes 3 references, figures.
